My best friend's sister's boyfriend's brother's girlfriend heard from this guy who knows this kid who's going with the girl who saw the 5D3's light leak at 31 Flavors last night. I guess it's pretty serious.

I just called Canon tech assistance and CPS. They say its a BS rumor. NOTHING AT ALL. THERE WILL BE A firmware UPDATE FOR THE 800MM LENS. Called national camera exchange they said they have heard nothing at all.

I called Kenmore camera here in Seattle and they hadn't heard anything about it, no emails/calls from Canon. If there is an issue it may be narrowed down to a small batch and they only contacted the vendors that the batch went to.

Maybe, but 800/5.6 and 200/2 owners are few so I doubt a camera wide re-call.

No matter how few owners there are, if that problem exists and it's a mechanical problem that needs to be fixed in the camera, they have to recall everything out there right? It doesn't make sense to me if they just recall from those who have the lenses in question. So you'd prefer to send in yours later when you plan to get 200 f/2 IS ?
